Description

Technical Field

[0001] This invention relates to the field of lock cylinder technology, and specifically to a novel highly waterproof electronic lock cylinder structure. Background Technology

[0002] The existing technology for the lock cylinder structure of electronic locks generally includes a lock shell, a rotating shaft, a handle, a transmission mechanism, and a transmission component. The lock shell is fitted onto the rotating shaft, the transmission component is located at one end of the rotating shaft, and the other end of the rotating shaft is equipped with a fixed seat, which is connected to the handle. The fixed seat and the handle are generally fixed by multiple screws.

[0003] For example, the patent filed by this applicant on March 1, 2019, publication number CN109667485A, entitled "An Electronic Lock Cylinder," see its appendix. Figure 1-4 As shown, the fixing seat is secured by screws on the side wall of the handle; another example is the patent filed by the applicant on August 27, 2020, publication number CN213510016U, entitled "An Adjustable Length Electronic Lock Cylinder," see its appendix. Figure 1-4 As shown, the mounting base is also secured by screws on the side wall of the handle; another example is patent CN209837953U, entitled "A Mechanical-Electronic Fingerprint Lock Core," see its appendix. Figure 2-4 As shown, the lock cylinder rear cover 17 (i.e., the mounting base) is fixed to the lock cylinder outer cover 1 (i.e., the handle) from the end by multiple screws.

[0004] However, fixing with screws generally has the following problems: 1. Poor sealing, water can easily enter through the screw holes; 2. Inconvenient installation, requiring multiple screws for fixing, making the operation troublesome and cumbersome; 3. Poor protection performance, as the threads are generally universal screws, so ordinary people can directly use common and simple tools to disassemble them. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a novel highly waterproof electronic lock cylinder structure.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0011] In some embodiments, a second annular groove is provided on the inner wall of the connection port, and the outer wall of the seal abuts against the second annular groove.

[0012] In some embodiments, the elastic element is a wave spring washer, which is sleeved on the connecting shaft.

[0013] In some embodiments, a disassembly locking part extending axially is provided at the outer end of the connector, the disassembly locking part can cooperate with a specific special tool, and the disassembly locking part can be driven to rotate by the special tool.

[0014] In some embodiments, the disassembly locking part includes a circular body, the outer wall of which is provided with a plurality of slots evenly distributed along the circumference, and the special tool is a crescent wrench.

[0015] In some embodiments, a transmission assembly is provided on the lock housing and at the end of the rotating shaft.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. First, the traditional screw fixing structure is abandoned. The fixing part is set as a sealing seat and a connecting seat. The sealing seat ensures the sealing between the handle sleeve and the handle sleeve. Then, the connecting seat is threadedly connected to the handle sleeve for fixing. The installation is very convenient and quick.

[0019] 2. Furthermore, by setting an elastic element between the sealing seat and the connecting seat, the elastic element generates a downward force on the sealing seat, thereby making the sealing element tightly fit against the inner wall of the connecting port of the handle sleeve, which greatly improves the sealing performance. At the same time, the elastic element generates an upward thrust on the connecting seat, thereby making the connecting seat and the threads on the connecting port tightly fit together, preventing the connecting seat from loosening accidentally and ensuring the stability after installation.

[0020] 3. In addition, a disassembly locking part is provided at the upper end of the connector. This disassembly locking part can only be turned by a specific special tool, so that ordinary people cannot turn the connector open at all, which greatly improves the security performance of the lock cylinder.

[0028] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0029] The invention will be further described below with reference to the accompanying drawings and specific embodiments: as follows: Figures 1-7 The novel highly waterproof electronic lock cylinder structure shown includes a lock housing 1, a handle sleeve 2, and a rotating shaft 3 disposed within the lock housing 1. One end of the rotating shaft 3 is provided with a fixing part 4, and one end of the handle sleeve 2 is provided with a connection port 10. The fixing part 4 is mounted on the connection port 10. The fixing part 4 includes a sealing seat 5, a connecting seat 6, and an elastic element 7. The sealing seat 5 is disposed within the connection port 10, and its outer wall is provided with a sealing element 8 that maintains a tight seal with the inner wall of the connection port 10. The connecting seat 6 is threadedly connected to the connection port 10, and the elastic element 7 is disposed between the sealing seat 5 and the connecting seat 6.

[0030] In this invention, the traditional screw fixing structure is abandoned first. The fixing part 4 is set as a sealing seat 5 and a connecting seat 6. The sealing seat 5 ensures the sealing with the handle sleeve 2. Then, the connecting seat 6 is threadedly connected and fixed to the handle sleeve 2. The installation is very convenient and quick.

[0031] Furthermore, by providing an elastic element 7 between the sealing seat 5 and the connecting seat 6, the elastic element 7 exerts a downward pressure on the sealing seat 5, thereby causing the sealing element 8 to fit tightly against the inner wall of the connecting port 10 of the handle sleeve 2, which greatly improves the sealing performance. At the same time, the elastic element 7 exerts an upward thrust on the connecting seat 6, thereby causing the connecting seat 6 to fit tightly against the threads on the connecting port 10, preventing the connecting seat 6 from loosening accidentally and ensuring the stability after installation.

[0032] In addition, a disassembly locking part 71 is provided at the upper end of the connecting seat 6. This disassembly locking part 71 can only be turned by a specific special tool 72, so that ordinary people cannot turn the connecting seat 6 open at all, which greatly improves the security performance of the lock cylinder.

[0033] See Figures 1-4 As shown, a plurality of longitudinal guide grooves 21 are evenly distributed along the circumference on the inner wall of the connection port 10, and a plurality of guide flanges 22 corresponding to the longitudinal guide grooves 21 are provided on the outer wall of the sealing seat 5. During installation, the sealing seat 5, the connecting seat 6 and the handle sleeve 2 are installed along the longitudinal guide grooves 21 through the guide flanges 22, which can ensure that the sealing seat 5, the connecting seat 6 and the handle sleeve 2 are on the same axis, and can allow the connecting seat 6 to be smoothly threadedly connected to the connection port 10.

[0034] Specifically, the outer wall of the connector 6 is provided with external threads, while the inner wall of the connector port 10 is provided with internal threads.

[0035] Three sets of guide flanges 22 and longitudinal guide grooves 21 are provided respectively.

[0036] Furthermore, a connecting shaft 31 extending upward and used for connecting with the rotating shaft 3 is provided at the center of the sealing seat 5, and a through hole 32 is provided at the center of the connecting seat 6, which is movably sleeved on the connecting shaft 31; this facilitates the connection between the sealing seat 5 and the connecting seat 6, while ensuring their concentricity.

[0037] The elastic element 7 is a wave spring washer, which is sleeved on the connecting shaft 31. The wave spring washer makes the structure simple and easy to install.

[0038] See Figures 3-5 As shown, a first annular groove 41 is provided on the outer wall of the sealing seat 5, and the sealing member 8 is sleeved in the first annular groove 41, and the sealing member 8 is a silicone sealing ring.

[0039] Furthermore, a second annular groove 51 is provided on the inner wall of the connection port 10, and the outer wall of the sealing member 8 abuts against the second annular groove 51.

[0040] Of course, a step is also provided inside the connection port 10. After the sealing seat 5 is installed, it rests against the step, which facilitates the positioning of the sealing seat 5 and improves the sealing performance.

[0041] See Figure 1 , Figure 5 , Figure 6 As shown, a disassembly locking part 71 extending axially is provided at the outer end of the connecting seat 6. The disassembly locking part 71 can cooperate with a specific special tool 72 and be driven to rotate by the special tool 72.

[0042] Furthermore, the disassembly and locking part 71 includes a circular body 81, and the outer wall of the circular body 81 is provided with a plurality of slots 82 evenly distributed along the circumference, and the special tool 72 is a crescent wrench.

[0043] It should be noted that the arrangement of the circular body 81 and the groove 82, as well as the arrangement of the crescent wrench, are only preferred embodiments of this invention. However, the present invention is not limited to the above-described embodiments. As long as any similar or identical means are used to achieve the technical effects of the present invention, they should fall within the protection scope of the present invention.

[0044] In this invention, a transmission assembly is provided on the lock housing 1 and at the end of the rotating shaft 3. The transmission assembly includes a transmission component 91 and a transmission plate 92 detachably connected to the transmission component 91. The transmission component 91 is fixedly connected to the lock housing 1 by a snap ring 93.

[0045] The transmission plate 92 includes a connecting plate 94 and crimping portions 95 at both ends of the connecting plate 94. The end of the transmission member 91 is provided with a fixing groove 96. The crimping portion 95 is located in the fixing groove 96. A pressure ring 98 is connected to the upper end of the transmission member 91 by a screw 97. The pressure ring 98 restricts the crimping portion 95 within the fixing groove 96.

[0046] Therefore, different specifications of transmission plates 92 can be selected and replaced according to different lock requirements, thereby improving the practicality of the lock cylinder. In addition, the working principle of the transmission component is the same as that of the traditional lock cylinder, so it will not be described in detail here.
